Copy the DWO and then cd into the output directory, so that the symbolizer would
find the DWO if it attempted to.
RUN: rm -rf %t && mkdir -p %t

Built from the following source:
void f1();
__attribute__((always_inline)) inline void f2() { f1(); }
void f3() { f2(); }

Compiled to assembly with clang, modified the skeleton CU to remove the
high/low pc (& update the CU length field and abbrev to match) & then
compile/objcopy to make the .o and .dwo.

Ensure that the f2 inlined frame is not included - it's inefficient to have to
go and load all the debug info and search for the address ranges, so assume
that a lack of ranges on the CU means the CU covers no addresses.
